I didn't think I would ever want one either. They are expensive, take up a whole lotta room, and, and.....
I now have one after watching demos at Lancaster Quilt show. I got a floor model Viking with a Grace Frame and absolutely LOVE it. I did not get the computer. It has a stitch regulator which is WONDERFUL. I can do a simple meander on a charity quilt in an hour including mounting it on the frame. I don't plan to quilt for other people but that may also change. I will never be as good as Charisma but it sure is fun.
